About GBM and Sample types

[Seyma Bilgin]

Hi,

I am a new user of cBioPortal. I've been working on Glioblastoma multiforme studies. Does the ''Sample Type / Primary'' meaning one of the GBM subtypes such as ''Primer GBM'' ? Or does it point out different information ? 

Best regards,

Seyma Bilgin

Hi Seyma,

Sample Type of primary means the sample was from the primary tumor. Other types could be recurrence and metastasis.

Best,

Hi Jianjiong,

Thank you for that information. Additionally, I wonder about another thing. When I selected the Proneural subtype of GBM, the tables show that almost all patients have IDH wildtype. However, the Proneural type is known with %93 point mutation at IDH1. So how can we interpret this inconsistency?

Best regards,
